Patented. Apr. 25, 1922 Y THOMAS HUNT, or' ILKES-Jennn11, Ann ELMER summit, on rAnsons, PENN I SILK-DOUBLING MACHINE.

T 0 all whom it may concern: v .Be it known thatwe, TrroMAsHnNr' and ELMER STETLER, citizens of the United States, residing, respectively, Fin lVilkes-Barre and Parsons, in the county of Luzer'ne and State of Pennsylvania, have invented certain new and useful Improvements in Silk-Doubling Machines, of which the following is a specification.

This invention relates to machines in which silk is doubled by being wound on single spools, bobbins, or other receivers from a plurality of spools or other carriers of the material.

In some machines for that purpose, a plurality of spools or other carriers of the material forming the supply to the spools, bobbins, or other receivers on which the material is wound are supported on frames or the like arranged in substantially parallel relation to one another and at an inclination to the perpendicular.

When material from a spool or other carrier on a frame breaks, the loose end portion thereof is liable to, and frequently does, become involved with material passing from carriers on an adjacent frame, and the result is interference with the proper operation of the machine and faulty product wound on the receivers.

It is an object of the invention to avoid such occurrences by providing means to prevent broken or loose parts ofthe material fromcoming into such contact with properly moving material as will result in entan lement. Y Fhen read in connection with the description herein, the characteristics of the inven tion will be apparent from the accompanying drawing, forming part hereof, wherein an embodiment of the invention is dlsclosed, for purposes of illustration. 7

Specification of Letters Patent; Pja't td 'A 922 I 'ceivers Con which is wound silkmaterial pass ng throu h guides D from spools or other carrlers, on pins F [of frames G.

The frames are positioned in substantlally parallel relation to one another at-an lnclinatlon to the perpendicular, one above every guide D, and the material passing from the carriers converges as it moves to the guides. One reason for disposing the frames at an inclination is to avoid contact of the strands of material p-assingffrom the several carriers until it has reached or nearly reached the guides.

If a strand of material breaks between a carrier and a guide, the portion dependlng from the carrier is apt to, swing toward the carriers on the next adjacent frame toward which its own frame is inclined. If

breakage occurs near the bottom of a frame 1n material from an upper carrier, and thus. there is left a comparatively long depending free or loose portion, there is greater-liability of entanglement with material of the next adjacent frame than when the depending portlon is short, as, of course, the arc of With a view of preventing such entanglement, means are interposed by the invention between the frames. Each frame G has an arm 4: extending laterally therefrom toward the next adjacent frame, the arm preferably being. integral with its frame. A pin or spindle 5 extends from the free end portion of each arm, in substantially parallel rela tion to and of about-thesame length as the carrier-spindles F, A roller 6 is carried by and is rotatable oneach of the pins 5, and preferably it is of polished or smooth porcelain, as that material has been found capable I A roller so located operates to prevent the I depending port-ion of broken or loose mate- .rial from swinging over against material of an adjacent frame. For the reason hereinbefore explained, the rollers or guides are placed on lower portions of the frames as shown.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
